There is an application with an SPI radio module that gives me a "Ready" signal on MISO line, pulling up or down the line. Is it possible to configure those three gpio pins as SPI and at the same time read their levels in their relative IDR?

Hello,I'm designing an application where a PCB with STM32F031C6 has to receive a minimum of 5 bytes via an half-duplex communication. Transmission is delimited by special character, ASCII is used. Ideally, the transmission would be composed by 3 data...

Thanks! What do you mean by "use hw feature to detect the end character"? Which hw feature?

Thank you for the explanation!

I will probably stick with the classic method as you both said, placing the code in the stmxxx_it.c routine.

What do you mean for "is used for debug purpose"? What harm can cause a SYSTICK callback already initialized and running? If this exclusion is aimed to discourage the use of SYSTICK callback as main location of programming (to avoid problems as Clive...

Can SPI MISO pin state be read also in gpio's IDR?
